I had a conversation with a ghost while waiting to be treated in the local ER here in February of 2007.
I saw her for only a second or two, then she disappeared. She smiled at me and told me in my head that she was glad I saw her.
"What are you doing here?" I asked her.
She said that there was nowhere else to go.
I told her that it would be best if she crossed over into the Light.
"I can't."
"Why not?"
"Because I know what awaits me."
The doctor came in and I never heard from her again.
